The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

I denna studie har jag undersökt hur ledarskap på distans bedrevs av ledare med chefsuppdrag inom laboratoriemedicin. Syftet med studien var att undersöka hur cheferna beskrev vad som utmärkte ledarskapet på distans, vilka egenskaper en ledare behövde för att leda en organisation på distans och hur de kommunicerade med sina medarbetare.  Jag har i denna studie intervjuat åtta ledare på olika nivåer. Sex av informanterna arbetade inom två olika landsting och två arbetade åt en privat vårdgivare. Vid genomgången av intervjumaterialet framkom nio olika teman vilka var specifika egenskaper, delegering, resor, motivation och feed-back, avstämmande kommunikation, kommunikationsformer, mötesformer, medarbetarsamtal och information.

Automatic rumination measuring can be applied as a health indicator in dairy farming but is also highly desirable for research purposes. This study aimed to validate the technical functionality of the product RuminActTM, which employ acoustics to monitor rumination duration. The time budget of high yielding cows was studied and possible differences in rumination time between 13 rations were interpreted. Further the study examined what affects daily rumination and rumination efficiency. The validation was performed with direct observations that were compared to the automatically recorded rumination durations.

Bakgrund: Belöningssystem är idag ett hett ämne som det debatteras mycket om i media. Debatten berör främst den privata sektorns höga bonus till högt uppsatta chefer. Belöningssystemen är idag inte lika etablerade inom den offentliga sektorn som de är inom den privata sektorn beroende på att finansieringen inom den offentliga sektorn är mer begränsad än inom den privata sektorn. Medarbetare inom den offentliga sektorn drivs inte enbart av pengar utan det är andra faktorer som skapar drivkraft. Syfte: Syftet med uppsatsen är att studera befintliga belöningssystem för lärare inom Linköpings kommunala gymnasieskolor.

The purpose with this study was to analyze the possibilities to produce organic lambs and to hihglight the most common difficulties in such a production system. A description of current organic and conventional lamb production systems was conducted, both from Sweden and from some other countries. The Department of Animal Environment and Health at SLU in Skara performed the project together with The County Board of Agriculture in Västra Götaland and Värmland and The Swedish Animal Health Service. The project lasted from 2002 to 2004. The student report contains the years 2002 and 2003. In the year of 2003 there were 210 000 adult sheep in Sweden, of which 16 400 adult sheep were certified by KRAV. Of the different countries in Sweden, Västra Götaland and Gotland had the largest number of sheep, 14 and 13 per cent of the total number.

Calf health is of importance both from a financial perspective and from an animal welfare point of view. Housing system and environment are factors affecting the calves? health. The objective of this project was to make a review of literature on calf health and housing and to perform an observational study on calf health at Nötcenter Viken, Research Dairy Farm, Lantmännen Sweden that changed calf housing system; from a traditional indoor system (Group IN) to outdoor hutches (Group OUT). It was only the housing system that was changed; the routines and feed were the same in both systems.

Relationship between social behaviour, feeding behaviour and performance of boars using single-space feeders A study on the behavioural patterns of growing boars is presented. The study was preformed at Quality Genetics? boar testing station Månseryd in Sweden. The boars were purebred Yorkshire, Hampshire or Landrace, born in nine different nucleus farms. The study is based on two batches of boars, with 63 and 69 boars respectively.

The aims with the project were to investigate how forage consumption affect production and pigs behaviour around the feeding. This degree project was designed to follow 48 growing/finishing Hampshire*Yorkshire pigs, from 30-110 kg live weight, fed diets with or without 20 % forage inclusion. The pigs were divided in three groups due to dietary treatment. In the first group the pigs were fed 20 % of the energy in the feed ration by long grass/clover silage (LE) and the remaining 80 % by a cereal concentrate. Group two was fed chopped grass/clover silage mixed with cereal concentrate (HE) in the same amounts as LE.

With the curriculum Lpfö98, and its revised version 2010, the demands for evaluation of the quality of the preschool have been emphasized. Accordingly, the activities need to be systematically documented, followed up and assessed, to be improved. Most importantly, this includes continuous follow up, documentation and analysis of the development and learning of the children. This is usually carried out by means of pedagogical documentation, but how this working tool should be used in practice is not totally clear for all pedagogues. The aim of this study was therefore to investigate how pedagogical documentation is performed, assessed and made accessible for the children, parents and staff-members, in practical preschool work.In the study, four pedagogues (two preschool teachers and two pedagogical mentors), working in two different preschools where the Reggio Emilia concept is practiced for pedagogical documentation, were interviewed using a semi-structured questionnaire.The informants described pedagogical documentation as a complex and time-consuming working tool, albeit necessary and helpful to fulfill the requirements of the curriculum.

The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today. This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.

AbstractThe Northern Wheatear (Oenanthe oenanthe) is a small insectivorous passerine bird living in open landscapes. Both parents feed the brood of approximately five chicks, but little is known about how each sex allocates their feeding effort. In this study I investigate feeding nest visit differences between male and female Northern Wheatears relative to the age of the chicks, the number of chicks and the quality of the territory for 17 pairs from 2008-2010. Data were collected using automated data loggers to record nest visitation rates during chick feeding, and the sex was determined from nest video cameras. I also examine if the parents? rate of feeding visits changes over the nestling period.

The background to this paper is the fact that many products are demonstrated to show the consumer value of the product. This is generally the fact when it comes to agricultural products, such as tractors. The growing number of models makes this even more import for the retailer to perform a demonstration that really catches the interest of a prospect customer. One problem is that these demonstrations are expensive and many small retailers have difficulties to afford demonstrations of every model. Together with Åhmans Traktorcentrum AB a market investigation was conducted. The company has its primary sales area in the region of Östergötland and north part of Småland. Åhmans Traktorcentrum AB is a John Deere dealer.

Syfte: Hur uppfattar elever att lärare använder datorn i undervisningen?Teori: Med en-till-en, den personliga datorn utmanas det traditionella lärandet. Ett digitaliserat lärande innebär att lärarna ska planera för lärande och inte för undervisning (Kroksmark, 2012).Metod: En kvalitativ intervjumetod, ostrukturerad intervju, användes för att samla in resultatet, som analyserades med kvalitativ innehållsanalys. Fyra kategorier framkom: datorn i undervisningssammanhanget, instruktioner från lärare, elevernas interaktion med en-till-en och slutligen lärares bedömning av elevarbeten. Resultat: Studien visar att eleverna uppfattar att lärarna använder datorn till att visa film, visa Key-Notespresentationer vid genomgångar.

In Sweden regulations stipulates that dairy cows are kept on pasture, or given the opportunity to spend time outside during a coherent period of between two to four months, depending on region. The transition out to pasture is a big change from the winter period in the stable, especially for the modern high yielding dairy cows. The let out to pasture includes a change in feed, environment, and new routines. There are indications that the milk somatic cell count (SCC) rises in a peak shortly after the let out. The purpose of this study was to see if peaks in the SCC could be observed after the let out, and to study the contribution of inflammatory cells (neutrophils) and if the milk composition are affected. The study included 35 cows that were kept in stable during the winter.

Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.
